Introduction: In this study the synthesis and characterization of copper oxide nanoparticles via solid state thermal decomposition of a recently synthesized aqua nitrato copper(II) complex with a tridentate Schiff-base ligand (1) as a new precursor are reported. Materials & Methods: The copper complexes were obtained by sonochemical and solvothermal process and characterized by Scanning Electron Microscopy (SEM), X-ray powder Diffraction (XRD) and FT-IR spectroscopy. The thermal stability of compound (1) was studied by Thermogravimetric Analysis (TGA). The amount of initial reagents and the role of reaction time on size and morphology of nanostructure compound (1) were studied. CuO nanoparticles were simply synthesized at 500 oC under air atmosphere. Results & Conclusion: The diameter of CuO nanoparticles was estimated to be about 200 and 30 nm from copper complex precursor obtained by sonochemical and solvothermal methods respectively.

AbstractSynthesis and structural characterization of two heterodinuclear ZnII-LnIII complexes with the formula [ZnLn(HL)(µ-OAc)(NO3)2(H2O)x(MeOH)1-x]NO3 · n H2O · n MeOH [Ln = Pr (1), Nd (2)] and the crystal and molecular structure of [ZnNd(HL)(µ-OAc)(NO3)2(H2O)] [ZnNd(HL)(OAc)(NO3)2(H2O)](NO3)2 · n H2O · n MeOH (3) are reported. The asymmetrical compartmental ligand (E)-2-(1-(2-((2-hydroxy-3-methoxybenzylidene)amino)-ethyl)imidazolidin-2-yl)-6-methoxyphenol (H2L) is formed from N1,N3-bis(3-methoxysalicylidene)diethylenetriamine (H2valdien) through intramolecular aminal formation, resulting in a peripheral imidazoline ring. The structures of 1–3 were revealed by X-ray crystallography. The smaller ZnII ion occupies the inner N2O2 compartment of the ligand, whereas the larger and more oxophilic LnIII ions are found in the outer O2O2’ site. Graphic Abstract Synthesis and structural characterization of two heterodinuclear ZnII-LnIII complexes (Ln = Pr, Nd) bearing an asymmetrical compartmental ligand formed in situ from N1,N3-bis(3-methoxysalicylidene)diethylenetriamine (H2valdien) through intramolecular aminal formation are reported.
